Once I finished the retopolgy I started on UV mapping. I tried my best marking out the seems on each section of the model. I hid the seems when possible, which was easiest t0 do on the hair, as I can have a seem in the inner part of the hair. Unfortunately, I later found out the UV on the hair had been altered between files when exporting them from my laptop to my Mac mini.  I am not sure where the change happened or how as I didn’t touch the UV on the hair after I originally made the UV and no other UV’s on the model were changed.

I later went back to change the UV to UDMIS but decided to change the UV back to just a single UV title.  When I went to texture in substance I couldn’t figure out how to texture the model as I couldn’t interact with the additional UV titles.

Looking back at my model some how all the seems have disappeared however, the UV are still there so texturing an adding the textures on to the model  thankfully wasn’t a problem.  The hair UV has somehow been altered which may have been the cause of the zipper marking on the hair textures.
